NCT ID NCT07720635

First seen Jul 22, 2026 · Last updated Jul 24, 2026 · Updated 2 times

Summary

This phase 3 trial tests whether the experimental drug KHN939 can reduce eye bulging and other symptoms in people with moderate-to-severe active thyroid eye disease. About 60 participants in China will receive either KHN939 or a placebo by infusion every three weeks for 21 weeks. The main goal is to see if the drug leads to a meaningful reduction in eye protrusion without worsening the other eye.
